  AN-173 IC Zener Eases Reference Design (Rev. B)
  PDF, 137 Kb, 修订版: B, 档案已发布: May 5, 2013
  A new IC zener with low dynamic impedance and wide operating current range significantly simplifies reference or regulator circuit design. The low dynamic impedance provides better regulation against operating current changes, easing the requirements of the biasing supply. Further, the temperature coefficient is independent of operating current, so that the LM129 can be used at

  AN-181 3-Terminal Regulator is Adjustable (Rev. B)
  PDF, 314 Kb, 修订版: B, 档案已发布: May 5, 2013
  Until now all of the 3-terminal power IC voltage regulators have a fixed output voltage. In spite of this limitation their ease of use low cost and full on-chip overload protection have generated wide acceptance. Now with the introduction of the LM117 it is possible to use a single regulator for any output voltage from 1.2 V to 37 V at 1.5A. Selecting close-tolerance outp

  Packaging Limits Range of Linear Regulators
  PDF, 75 Kb, 档案已发布: May 8, 2010
  The power limitations of the physical packaging for a linear regulator device can limit the total output current or the input-to-output voltage differential. This inherent limitation is not always apparent from the product data sheet and must be evaluated during the design phase. This application note shows how the package can limit the operating envelope of a linear regulator.
